MeasureRunWidth measured the width in eight shells of equal count in d*^2 and fitted the three-term
formula gamma0^2 + (gamma_e d*)^2 + (bw |q_z|)^2 to them. On runs predicting ~1000 reflections a frame
the equal-count shells all sat at 3.8-1.8 A, so the low-resolution width was the formula's
extrapolation, and the fit's form flipped with the number of frames (to a pure bandwidth at 50k frames).
The same window-group moment is now also measured in eight shells of equal width in d*, made
non-decreasing (pool adjacent violators, weighted by each shell's summed signal) and kept in RunWidth as
a table that the partiality interpolates linearly in d*. The formula is still fitted on the equal-count
shells and still sets the prediction window. With fewer than three measurable shells the formula is
used as before.
Still battery, 12 non-float sets, together with the sigma-following prediction window (the previous
